Side cured light-transmissive display system

Abstract

An invisible, light-transmissive display system with a light resistant material is provided. The light resistant material has a first side and a second side. Substantially invisible holes penetrate between the first surface and the second surface in a predetermined light-transmissive display pattern. The second surface is exposed to a side curing light that is substantially parallel to the second surface at the invisible holes thereadjacent. A light-conducting curable filler is applied into the invisible holes from the first surface. Surfaces of the light-conducting curable filler are cured in the invisible holes at the second surface with the side curing light. The remaining curable filler in the invisible holes is cured.

What is claimed is: 
     
       1. An apparatus, comprising:
 a housing structure having a first planar surface and a second planar surface; 
 at least one opening that extends from the first planar surface to the second planar surface; 
 light curable material formed in the at least one opening, wherein a surface of the light curable material is a cured planar surface, wherein the cured planar surface is formed in a common plane with the first planar surface, and wherein the light curable material also includes an uncured portion that extends from the cured planar surface to the second planar surface of the housing structure. 
 
     
     
       2. The apparatus defined in  claim 1 , wherein the cured planar surface is a solid surface. 
     
     
       3. The apparatus defined in  claim 1 , wherein the housing structure comprises an opaque material. 
     
     
       4. The apparatus defined in  claim 3 , wherein the opaque material comprises metal. 
     
     
       5. The apparatus defined in  claim 1 , wherein the light curable material comprises a light-transmissive and ultra-violet curable material. 
     
     
       6. The apparatus defined in  claim 1 , wherein the at least one opening has a diameter at the first planar surface that is less than 100 microns. 
     
     
       7. The apparatus defined in  claim 6 , wherein the at least one opening has a conical shape. 
     
     
       8. The apparatus defined in  claim 7 , wherein the at least one opening has an additional diameter at the second planar surface that is less than 40 microns. 
     
     
       9. A method of manufacturing an electronic device having a housing structure with a first housing surface and a second housing surface, the method comprising:
 forming at least one opening in the housing structure, wherein the at least one opening extends from the first housing surface to the second housing surface; 
 forming a light curable material in the at least one opening; and 
 forming a planar cured surface on the light curable material by curing a surface of the light curable material while leaving a portion of the light curable material uncured, wherein forming the planar cured surface comprises forming the planar cured surface in a common plane with the first housing surface. 
 
     
     
       10. The method defined in  claim 9 , wherein the first housing surface comprises a planar housing surface and wherein forming the planar cured surface in the common plane with the first housing surface comprises:
 forming the planar cured surface in a common plane with the planar housing surface. 
 
     
     
       11. The method defined in  claim 10 , wherein curing the surface of the light curable material comprises:
 curing the surface of the light curable material using light that is emitted in a direction that is parallel to the planar housing surface. 
 
     
     
       12. The method defined in  claim 9 , further comprising:
 curing the uncured portion of the light curable material. 
 
     
     
       13. The method defined in  claim 9 , wherein forming at least one opening in the housing structure comprises:
 forming the at least one opening with a diameter that is less than 100 microns. 
 
     
     
       14. The method defined in  claim 9 , wherein the light curable material comprises a light-transmissive and ultra-violet curable material and wherein curing the surface of the light curable material comprises:
 curing the surface of the light curable material using ultra-violet light.
